Discussion
Kent Sullivan,
The Windows 95 User Interface: A Case Study in Usability Engineering
, CHI 1996.
A case study of the iterative design process.
What are some of the important points?
Only 12 people on the entire Win 95 interface design team!
Sullivan
Case Study
Interesting points about early users:
Beginning users had problems with:
Finding
a non-visible program
, double-clicking to activate, using hidden menus, finding minimized windows,
file system hierarchy
Initially didn’t want to introduce too many new things
However, initial studies on 3.1 and the 95 prototype indicated that the starting point was just too poor, and more radical revision was needed.

Sullivan Case Study
Had an offsite and rethought everything.
The
need to rapidly iterate
Waterfall design method (compartmentalized; UI done at the end during quality assurance stage) would produce an unusable product.
Jettison the giant design spec
Encouraged closer interaction and “hallway” conversations
Sullivan Case Study
Had an offsite and rethought everything.
Method Adopted:
Find
most common tasks
, and test on those
Compare to a baseline (Windows 3.1)
Use rapid prototyping tools
Keep testing with users.
Focus on scaffolding (beginner -> intermediate-expert)
Give up on too much backwards-compatibility with 3.1
Continually inform outsiders as well as team members about the design
Sullivan Case Study
Fine tuning with usablity tests
Holistic interface test in the lab
64 phases of lab testing
Many
participants! (560 total)
Longitudinal
field study
Other testing on components
No detail of the orginal design for W95 was retained.
About Windows 3.1
… a good demonstration of what happens when usability is not taken into account
